Electric driving scooter

ABSTRACT

An electric driving scooter installed with a motor for driving one rear wheel is disclosed. One side of the car body has a seat fixed. One outer lower edge of the seat is pivotally installed with a driven wheel and the seat is installed with a battery set. Power of the battery set is transferred to a controller and the motor through electric wires. A bottom of the car body has an auxiliary battery set the power of which is transferred to the controller and the auxiliary battery set is connected to the battery set in parallel. Thereby, the user can select one of the battery sets by a controller.

FIELD OF THE INVENTION

[0001] The present invention relates to scooters, and particularly to anelectric driving scooter which has two battery sets as power supply sothat the scooter can be driven by a motor, and two battery sets are usedalternatively.

BACKGROUND OF THE INVENTION

[0002] The prior art scooters are powerless so that the drivers mustdrive the scooters by themselves with larger forces. Some electricdriven scooters are developed, see FIG. 1, so that the drivers can drivethe scooters easily and comfortably.

[0003] To make the scooter light and convenient, in general, theelectric driving scooters are light and thus the battery set used have asmall size. Thereby, a scooter with newly charged battery can be driveneasily and comfortably, but when it is driven for a long time, the userwill feel that it is difficult to drive the scooter since the power inthe battery set is too few to drive the scooter comfortably. This isespecially obviously when the scooter moves along an upwards inclinedpath.

[0004] Moreover, when the load is heavy, the torsion force of thescooter becomes large. Thereby, it is often that the scooter can be wellcontrolled. Thus, the prior art scooters can not be well controlled anddriven as the traveling path is long.

[0005] Further the prior art scooter is compact and the size thereof isfinite and thus it is inconvenient to carry heavy loads. From abovedescription, it is appreciated that the prior art scooter has finitefunctions and cannot be used widely.

SUMMARY OF THE INVENTION

[0006] Accordingly, the primary object of the present invention is toprovide an electric driving scooter, wherein the scooter has a seatwhich can be assembled to and detached from the car body. The seat canbe used to carry other member or other object.

[0007] Another object of the present invention is to provide an electricdriving scooter, wherein a battery set can be installed to the seat. Theseat can be detached from the car body for transfer. Moreover, the seatand car body have three wheels so that the scooter is steadier.

[0008] To achieve above object, the present invention provide anelectric driving scooter installed with a motor for driving one rearwheel. One side of the car body has a seat fixed. One outer lower edgeof the seat is pivotally installed with a driven wheel and the seat isinstalled with a battery set. Power of the battery set is transferred toa controller through electric wires; and power of the scooter can beswitched to be supplied to the motor. A bottom of the car body has anauxiliary battery set the power of which is transferred to thecontroller and the auxiliary battery set is connected to the battery setin parallel. Thereby, the user can switch the controller as necessary toselect one of the battery sets as a power supply or the two battery setssupply power at the same time.

[0009] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring to FIGS. 2 to 5, the electric driving scooter of thepresent invention is illustrated. The electric driving scooter 1 has amotor 11 for driving the rear wheel 12 so that the scooter 1 can moveforwards.

[0017] One side of the car body 13 has a seat 15 fixed by two studs 14.The outer lower edge of the seat 15 is pivotally installed with a drivenwheel 16 and the seat 15 is installed with a battery set 17. The powerof the battery set 17 can be transferred to a controller 18 throughwires 171. The power output of the scooter 1 can be switched by rotatinga handle 10 of the scooter 1 so that power can be supplied to the motor11.

[0018] With reference to FIG. 4, a bottom of the car body 13 has anauxiliary battery set 19 the power of which is transferred to thecontroller 18 and the auxiliary battery set is connected to the batteryset 17 in parallel. Thereby, the user can switch the controller 18 asnecessary to select one of the battery sets 17 or 19 as a power supplyor the two battery sets 17 and 19 can supply power at the same time.

[0019] When the scooter 1 moves along an upward inclined path, thebattery set 17 and battery set 19 can be actuated at the same time tosupply power to the motor 11. Thereby, the scooter 1 is driven with alarge power from the two battery sets.

[0020] When the scooter 1 moves along a flat or smooth path, only onebattery set 11 or 19 is used to supply power.

[0021] Two battery sets are used, thereby, the present invention cansupply larger power and the battery sets can be used alternatively sothat the times of charging are be reduced.

[0022] Moreover, in the present invention, the support frame 101 ofhandle of the scooter 1 according to the present invention can be foldedto the car body 13 for storage with a smaller volume. Of course, theseat 15 and car body 13 of the present invention can be detachedfrequently. Thereby, the present invention is a convenient design forthe scooters.

[0023] Although the present invention has been described with referenceto the preferred embodiments, it will be understood that the inventionis not limited to the details described thereof. Various substitutionsand modifications have been suggested in the foregoing description, andothers will occur to those of ordinary skill in the art. Therefore, allsuch substitutions and modifications are intended to be embraced withinthe scope of the invention as defined in the appended claims.
